Warnings

Tools required

Parts

• Replacement radio/head unit × 1 — Aftermarket or OEM 86100-06XXX series depending on trim level
• Radio wiring harness adapter × 1 — Required if installing aftermarket unit
• Radio antenna adapter × 1 — Required if installing aftermarket unit
• Radio mounting bracket kit × 1 — Required if installing aftermarket single-DIN unit

Preparation

1. Park vehicle on level surface and engage parking brake
2. Turn ignition to OFF position and remove key
3. Note radio presets and settings if desired
4. Gather all tools and replacement parts before beginning

Procedure

1. 1

   Disconnect battery negative terminal
   Open hood and locate battery in engine compartment. Using 10mm socket, loosen the negative (-) battery terminal bolt and remove cable from terminal. Secure cable away from battery post to prevent accidental reconnection. Wait 90 seconds minimum for airbag system to discharge.
   Torque spec

   Battery Terminal Bolts6 Nm (4 lb-ft)
2. 2

   Remove lower dashboard trim panel
   Locate the small trim panel below the radio/climate control area. Gently pry out the bottom edge using trim removal tool, working from one side to the other. Release the clips by pulling steadily outward. Remove panel and set aside in safe location.
3. 3

   Remove center console trim bezel
   Insert trim removal tool at the edges of the radio/climate control trim bezel (surrounding the radio and climate controls). Work around the perimeter to release approximately 8-10 retaining clips. Once clips are released, pull trim bezel straight back to disconnect any electrical connectors on the reverse side if equipped with additional switches. Set bezel aside.
4. 4

   Remove radio mounting screws
   With trim bezel removed, the radio unit is now visible. Locate and remove the four screws securing the radio to the dashboard mounting bracket (two on each side). These are typically 10mm hex head screws or Phillips head screws depending on production date.
5. 5

   Extract radio unit from dashboard
   Carefully pull the radio unit straight out from the dashboard opening. Pull out approximately 4-6 inches to access the rear connectors. Support the unit with one hand while working on connectors.
   ⚠Do not pull radio out too far or wiring harnesses may be damaged.
6. 6

   Disconnect radio harness connectors
   Locate the main wiring harness connector (large multi-pin connector), antenna cable connector, and any additional connectors (USB, AUX, microphone if equipped). Press the release tab on the main harness connector and pull straight out. Unscrew or unclip the antenna connector by pulling straight out. Disconnect any remaining connectors. Remove old radio unit completely.
7. 7

   Prepare new radio unit
   If installing aftermarket radio, attach wiring harness adapter to new radio according to adapter instructions. If installing OEM replacement, proceed directly to installation. For aftermarket single-DIN units, install mounting bracket kit to new radio. Ensure all connections on new unit are accessible.
8. 8

   Connect new radio harness
   Connect the main wiring harness to the new radio unit (or to the adapter harness if using aftermarket unit). Ensure connector clicks firmly into place. Connect antenna cable by pushing straight in until seated (or screwing on if threaded type). Connect any additional USB, AUX, or microphone connectors as applicable.
   ⚠Ensure all connectors are fully seated to prevent intermittent operation or error codes.
9. 9

   Test radio operation before final installation
   Temporarily reconnect battery negative terminal (hand-tight only). Turn ignition to ACC or ON position and verify new radio powers on, displays correctly, and all functions operate (AM/FM, speakers, Bluetooth if equipped). Test steering wheel controls if applicable. If everything functions correctly, turn off ignition and disconnect battery again.
10. 10

    Install radio into dashboard
    Carefully guide wiring harnesses into dashboard opening and push radio unit straight into mounting position. Ensure all wires are tucked behind radio and not pinched. Align mounting screw holes with dashboard bracket.
11. 11

    Secure radio mounting screws
    Install the four radio mounting screws and tighten evenly. Do not overtighten as this may crack the radio housing or dashboard bracket. Tighten screws in a cross pattern to ensure even seating.
12. 12

    Reinstall center trim bezel
    Reconnect any electrical connectors on back of trim bezel if applicable. Align bezel with dashboard opening and press firmly around perimeter until all clips snap into place. Verify bezel is flush and secure around entire perimeter.
13. 13

    Reinstall lower dashboard panel
    Align lower dashboard trim panel with mounting location and press firmly to engage all retaining clips. Ensure panel is fully seated and flush with surrounding trim.
14. 14

    Reconnect battery
    Reconnect battery negative terminal cable to negative post. Tighten battery terminal bolt to specified torque using torque wrench. Ensure connection is secure but do not overtighten.
    Torque spec

    Battery Terminal Bolts6 Nm (4 lb-ft)

Reassembly

1. All trim panels should sit flush with no gaps
2. Verify all dashboard trim clips are fully engaged
3. Check that radio mounting screws are tight but not over-torqued

Verification

• Turn ignition to ACC or ON position and verify radio powers on and displays correctly
• Test all radio functions including AM/FM tuner, volume control, and seek functions
• Test all speakers for proper output (front left, front right, rear left, rear right)
• Verify Bluetooth pairing and phone connectivity if equipped
• Test steering wheel audio controls for proper operation
• Verify USB and AUX input functionality if equipped
• Check that radio illumination dims properly with dashboard dimmer control
• Ensure no warning lights or error messages appear on instrument cluster
• Verify backup camera display functions properly when shifting to reverse (if equipped)
